Built by Base EA support

June 29, 2026 Sara Altuna CEO @ Base

Behind every exceptional EA is a leader who gave them their first opportunity.

Plenty of people have the judgment and the drive for EA work and never get a first opening. About 2% of invited applicants pass Base’s application process. Some of them clear every bar we set, professionalism, skills, judgment, drive, just with no EA experience on their resume yet. What they need is a first partnership.

That’s Built by Base.

How it works: you’re paired with an EA who has already passed our assessment and our interview, at $45 an hour. We onboard, train, coach, and mentor them, so your support meets Base’s standard from day one. You get excellent support at a lower price. They get the start of a career.

The bar doesn’t move. Every Built by Base EA clears the same application process every Base EA clears.

I know what that first yes is worth, because I got one. In 2018 I was finishing a degree and needed something flexible and remote. I barely understood what the role was, but Base took a chance on me and hired me as an Executive Assistant.

I learned fast that the job is bigger than it looks. A great EA has sharp judgment, anticipates what’s coming, stays calm when things get hard, and helps their leader see the whole picture. I stayed for the creativity and the critical thinking it took every day. Eight years later I’m the CEO of Base.

How one opportunity can change everything

Last year, #until2072 put investment behind women leaders. Built by Base starts at the beginning of a career: it backs the aspiring EA who needs one opening.

I needed someone to say yes first. So does every EA in this program. If you want excellent EA support at a more accessible cost, we’d love to work with you.
